Data Processing --------------- SeaCat salinity is prone to error due to a mismatch of conductivity and temperature response times, especially when the descent rate is non-uniform. Such errors are likely to be larger than calibration errors. SeaCat salinity errors are expected to be as high as 0.05 units in areas of high gradients. For these data the descent rate was very noisy for a few casts in the middle part of the cruise, but quite steady for most casts and temperature and salinity gradients were not extreme, so the error is likely much smaller than that. Salinity calibration sampling was done but no analysis results could be found at the time of processing. Post-cruise calibration results for salinity suggest that salinity calibration is well within +/- 0.002. There was no dissolved oxygen calibration for this cruise. Dissolved oxygen saturation at the surface suggests that the oxygen sensor might have been reading a little low. Based on a previous cruise the SBE DO data were recalibrated by multiplying by 1.04. The dissolved oxygen, transmissivity, fluorescence and turbidity data are nominal and unedited except that some records were removed in the course of editing temperature and salinity. ------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !-------------------------------- --------- ---- ------ ------------ 'Oxygen:Dissolved:SBE [mL/L]' mL/L 10 -99 () (0 1.04) 'Oxygen:Dissolved:SBE [umol/kg]' umol/kg 10 -99 () (0 1.04) $END !--1--- ---2---- --3-- ---4--- --5--- ---6---- --7--- --8-- -9-- !Pressu Temperat Trans Fluores Turbid Salinity Oxygen Oxyge Numb !re ure: missi cence: ity: :T0:C0 : n: er_o !
